The headline feature of EF to E CINE Smart Adapter and EF to E CINE Speed Booster ULTRA is a positive-lock EF lens mount carried over from the critically acclaimed Metabones EF-FZ CINE Smart Adapter, a perfect companion to the positive-lock mount of the new Sony FS7 Mark II camera.

All 4 new products are equipped with a rubber gasket to protect the E-mount connection from dust and moisture. To promote ease-of-use, an LED indicates the adapter's operation mode, optical image stabilization operation and communication status. A dedicated switch controls in-body image stabilization (IBIS) on Sony cameras equipped with SteadyShot INSIDE.

Metabones recounts the beginnings of the world's first fully electronic EF to E mount adapter 5 years ago, with only aperture control and auto-magnify (requires lens with distance information) but no autofocus support back then. Over the years firmware work has significantly expanded its capabilities. Today, the very same original Smart Adapter, though long discontinued, can still be upgraded to leverage the latest firmware benefits such as smooth iris (lens support required), fast contrast detection autofocus on all E-mount cameras, eye-AF, direct manual focus (DMF), zoom and distance display (requires lens with distance information), assignable custom button and 5-axis image stabilization (requires camera support).

Since the advent of the original EF to E Smart Adapter 5 years ago, Metabones has assumed a pivotal role in the mirrorless revolution. Cinematographers and photographers all over the world are armed with unprecedented flexibility of lens and camera choice.

EF to E CINE Smart Adapter will be available in February 2017 for USD 449 plus applicable taxes, duties and shipping, and EF to E CINE Speed Booster ULTRA will be offered at the same time for USD 699 plus applicable taxes, duties and shipping. Availability and pricing of EF to E Smart Adapter V and EF to E Speed Booster ULTRA II are to be determined.

Metabones®, together with its allied partners Caldwell Photographic and WB Design, is the pioneer and leader of two key technologies which have catalyzed the transition from mirror to mirrorless. Speed Booster® (winner of the 2013 TIPA Best Photo Accessory Award) makes lenses brighter, wider and sharper, and Smart Adapter™ breaks the lens mount compatibility barrier by electronically integrating interchangeable single-lens reflex (SLR) lenses and mirrorless cameras. Metabones® offers a comprehensive range of adapters covering most popular lens mounts, as well as some rare and exotic ones. "Always at the forefront of innovation without ever setting aside practicality as a professional tool" perhaps best epitomizes Metabones' philosophy.
